FIG. 1 is a block diagram illustrating an example of an exercisefeedback provision apparatus 100. Referring to FIG. 1 , the exercisefeedback provision apparatus 100 includes an acquirer 110, a controller120, and a feedback provider 130.

The acquirer 110 acquires exercise intensity information of a user.While exercising, the user may be under strain by performing a movement.Exercise intensity may indicate a level of strain affecting a body ofthe user. The acquirer 110 may acquire information of the body changeddue to the strain. As an example, user biometric information including,for example, a heart rate, an oxygen intake, and a maximum oxygen intakeof the user may be changed while exercising. Also, user movementinformation including, for example, a moving speed and a step count ofthe user may be changed while exercising. The acquirer 100 may acquireuser heart rate information, user moving speed information, and userstep count information.

The acquirer 110 may acquire the user biometric information, using aheartbeat sensor, for example, a photoplethysmography (PPG). Also, theacquirer 110 may acquire the user movement information, using anacceleration sensor.

The controller 120 verifies whether the acquired exercise intensityinformation is in a target range, i.e., a predetermined range. Theexercise intensity information of the user may change while exercising;for example, the heart rate of the user may increase. Also, the movingspeed of the user may increase during the exercise. For example, thecontroller 120 may verify whether the heart rate or the moving speed ofthe user is in the target range.

The controller 120 may set the target range based on the heart rate ofthe user. In this example, the target range may be a range of the heartrate. As an example, the controller 120 may estimate a maximum heartrate of the user based on an age of the user, and set 60% through 70% ofthe estimated maximum heart rate as the target range. As anotherexample, the controller 120 may verify the maximum heart rate of theuser within a predetermined period of time from a point in time at whichthe user starts the exercise, for example, within five minutes after theuser starts exercising. Based on the verified maximum heart rate, thecontroller 120 may adaptively set the target range. As still anotherexample, the controller 120 may set the target range based on a heartrate of an anaerobic exercise threshold. Using a communicationinterface, the acquirer 110 may acquire the heart rate of the anaerobicexercise threshold extracted based on a change in an electromyogram(EMG) signal of the user. The exercise feedback provision apparatus 100may transmit, to a server, a request for the heart rate of the anaerobicexercise threshold of the user, and receive, from the server, the heartrate of the anaerobic exercise threshold of the user. Using thecommunication interface, the acquirer 110 may also acquire the heartrate of the anaerobic exercise threshold of the user from a devicepaired with the exercise feedback provision apparatus 100.Alternatively, the acquirer 110 may verify the heart rate of the user byan exercise period expiring, and extract a heart rate corresponding tothe anaerobic exercise threshold from the verified heart rate. Thecontroller 120 may determine the extracted heart rate as the heart rateof the anaerobic exercise threshold, and set the target range based onthe determined heart rate of the anaerobic exercise threshold.

Based on a result of the verifying of whether the exercise intensityinformation is in the target range, the controller 120 may generate acontrol signal. As an example, the controller 120 may generate a firstcontrol signal when the acquired exercise intensity information isverified to be greater than the target range. The controller 120 maygenerate a second control signal when the acquired exercise intensityinformation is verified to be within the target range. The controller120 may generate a third control signal when the acquired exerciseintensity information is verified to be less than the target range. Thecontroller 120 may generate a diversified control signal such that theuser receives various forms of exercise feedback. As another example,the controller 120 may generate a control signal when the acquiredexercise intensity information is verified to be within the targetrange. When the acquired exercise intensity information is verified tobe outside the target range, the controller 120 may generate a controlsignal different from the generated control signal. In either of theaforementioned cases, the controller 120 may generate a diversifiedcontrol signal such that the user receives various exercise feedbacks.

The feedback provider 130 outputs a tactile feedback based on an outputpattern corresponding to the control signal generated by the controller120. For example, when the acquired exercise intensity information isverified to be greater than the target range, and when the controller120 generates the first control signal, the feedback provider 130 maydrive a vibration motor based on a first output pattern corresponding tothe first control signal. In addition, when the acquired exerciseintensity information is verified to be within the target range, andwhen the controller 120 generates the second control signal, thefeedback provider 130 may drive the vibration motor based on a secondoutput pattern corresponding to the second control signal. Also, whenthe acquired exercise intensity information is verified to be less thanthe target range, and when the controller 120 generates the thirdcontrol signal, the feedback provider 130 may drive the vibration motorbased on a third output pattern corresponding to the third controlsignal. The feedback provider 130 may output the tactile feedback basedon the output pattern corresponding to the control signal generated bythe controller 120, thereby providing various exercise feedbacks to theuser.

As another example, the controller 120 may divide a range including theexercise intensity information into a target range and a range otherthan the target range. The controller 120 may generate a control signalwhen the exercise intensity information is verified to be within thetarget range, and generate a control signal different from theaforementioned control signal when the exercise intensity information isverified to be outside the target range. In either of the aforementionedcases, the feedback provider 130 may output distinguishable tactilefeedbacks.

The exercise feedback provision apparatus 100 may further include acommunication interface configured to receive the output pattern from anexternal device. The communication interface may include, for example, awireless Internet interface such as a wireless local area network(WLAN), a wireless fidelity (WiFi) direct, a digital living networkalliance (DLNA), a wireless broadband (WiBro), a world interoperabilityfor microwave access (WiMAX), and a high speed downlink packet access(HSDPA), and a local communication interface such as a Bluetooth™module, a radio frequency identification (RFID) tag, an infrared dataassociation (IrDA), an ultra wideband, a ZigBee, and a near fieldcommunication (NFC). Also, the communication interface may include anyinterface, for example, a wired interface, capable of communicating withan external source.

The external device may be a device connected to the exercise feedbackprovision apparatus 100 using the communication interface. For example,the external device may be a wearable device and/or a mobile terminalpaired with the exercise feedback provision apparatus 100.

The external device may set the output pattern of the tactile feedbackoutput from the exercise feedback apparatus 100 based on a user input.For example, the external device may include a touch display, anddisplay a user interface for setting the output pattern on the touchdisplay. The user may apply the input to the user interface displayed onthe touch display, and the external device may sense a touch eventoccurring in response to the input. The external device may set theoutput pattern in response to the sensing of the touch event.

For example, the external device may display the interface for settingthe output pattern corresponding to each of the cases in which theexercise intensity information is greater than the target range, thetarget range, and less than the target range. That is, based on theinput of the user, the external device may set the output patterncorresponding to the case in which the exercise intensity information isgreater than the target range, and set the output pattern correspondingto the case in which the exercise intensity information is less than thetarget range. Also, the external device may set the output patterncorresponding to the case in which the exercise intensity information isin the target range, based on the input of the user.

Concurrently with the setting of the output pattern in the externaldevice, the exercise feedback provision apparatus 100 may output thetactile feedback based on the set output pattern. For example, the usermay set a pattern of a vibration output from the wearable device, usingthe mobile terminal. Concurrently with the setting of the pattern of thevibration, the wearable device paired with the mobile terminal mayoutput the vibration based on the set pattern. The user may verify thepattern of the vibration set by the user, and modify the pattern of thevibration using the mobile terminal.

The exercise feedback provision apparatus 100 may further include a userinterface configured to receive a selection input for setting the outputpattern from the user. For example, the exercise feedback provisionapparatus 100 may include a touch display to receive a touch input fromthe user. Based on the touch input of the user, the exercise feedbackprovision apparatus 100 may set the output pattern of the tactilefeedback.

The controller 120 may adaptively generate an additional output patternbased on the acquired exercise intensity information. For example, aheart rate corresponding to the target range may be “100” through “120”.When a heart rate of a user doing exercise is “130”, the controller 120may verify that the heart rate of the user is greater than the targetrange, and output the tactile feedback based on the output patterncorresponding to the result of the verifying. In this example, the usermay not decrease a running speed despite an output of the tactilefeedback. The controller 120 may sense that the exercise intensityinformation is not changed, and adaptively generate the additionaloutput pattern based on a result of the sensing. Based on the additionaloutput pattern, the feedback provider 130 may additionally output atactile feedback, a visual feedback, and an auditory feedback such thatthe user decreases the running speed in response to the additionaloutputting.

As another example, when the user increases the running speed althoughthe heart rate of the user is greater than the target range, thecontroller 120 may sense that the exercise intensity information is notchanged in a desired direction. The controller 120 may adaptivelygenerate the additional output pattern indicating the user is todecrease the running speed. The feedback provider 130 may additionallyoutput the tactile feedback, the visual feedback, and the auditoryfeedback based on the additional output pattern.

The feedback provider 130 may output at least one of the visual feedbackand the auditory feedback based on the output pattern. The exercisefeedback provision apparatus 100 may include a display and alight-emitting diode (LED). The LED may emit lights based on the outputpattern. Also, a message indicating the user is to increase a speed maybe displayed on the display, and an alarming sound may be output.

The controller 120 may sense a user manipulation corresponding to asuspension of outputting the tactile feedback. For example, thecontroller 120 may sense an action of the user covering the exercisefeedback provision apparatus 100, using a hand. In response to thesensing, the controller 120 may suspend the outputting of the tactilefeedback. Also, the controller 120 may sense at least one of a change ina contact resistance between the exercise feedback provision apparatus100 and the user, and a change in a contact level between the exercisefeedback provision apparatus 100 and the user. The controller 120 maysuspend the outputting of the tactile feedback in response to thesensing.

FIGS. 2 and 3 are diagrams illustrating examples of a pattern of anexercise feedback. Referring to FIG. 2 , a user may set a pattern of anexercise feedback, using a mobile terminal 200. An exercise feedbackprovision apparatus may receive the set pattern, using a communicationinterface. When a predetermined condition is satisfied, the exercisefeedback provision apparatus may provide the exercise feedback based onthe pattern.

When exercise intensity information including at least one of userbiometric information and user movement information is beyond a targetrange, a pattern corresponding to a case in which the exercise intensityinformation is greater than the target range, and a patterncorresponding to a case in which the exercise intensity information isless than the target range, may be set. In this example, the targetrange may correspond to an optimal exercise intensity of the user. Theuser may efficiently do an exercise at the optimal exercise intensity.For example, the target range may be a range of a target heart rate setbased on a heartbeat of the user. Alternatively, the target range may bea range of a moving speed corresponding to the range of the target heartrate of the user.

The moving terminal 200 displays a user interface for setting avibration pattern 1 210, a vibration pattern 2 220, and a vibrationpattern 3 230.

In FIG. 2 , the vibration pattern 1 210 may be an exercise feedbackcorresponding to the case in which the exercise intensity information ofthe user is greater than the target range. The vibration pattern 1 210is “10000000”. When the vibration pattern 1 210 is output from theexercise feedback provision apparatus, the user may decrease the movingspeed such that the exercise intensity information is within the targetrange.

The vibration pattern 2 220 may be an exercise feedback corresponding tothe case in which the exercise intensity information of the user is lessthan the target range. The vibration pattern 2 220 is “10101010”. Whenthe vibration pattern 2 220 is output from the exercise feedbackprovision apparatus, the user may increase the moving speed such thatthe exercise intensity information is within the target range.

The vibration pattern 3 230 may be an exercise feedback corresponding tothe case in which the exercise intensity information of the user iswithin the target range. The vibration pattern 3 230 is “00000000”. Whenthe heart rate or a running speed of the user is within the targetrange, the exercise feedback provision apparatus does not provide theexercise feedback. Alternatively, the vibration pattern 3 230 may be setas “11111111”. When the vibration pattern 3 230 is set as “11111111”,and when the exercise intensity information of the user is within thetarget range, an output of a tactile feedback may be performedcontinuously. When the tactile feedback is continuously output, the usermay pay attention to the tactile feedback during the exercise. The usermay apply an input to the exercise feedback provision apparatus suchthat a set value of the vibration pattern 3 230 is changed. The user mayperform a motion of covering the exercise feedback provision apparatus,using a hand during a predetermined period of time. Through this, theexercise feedback provision apparatus may sense the motion of the user.In response to the sensing, the exercise feedback provision apparatusmay change the set value of the vibration pattern 3 230. The exercisefeedback provision apparatus may output the tactile feedback based onthe changed set value.

The setting of the pattern for the exercise feedback may include settingan output speed of the tactile feedback. Alternatively or additionally,the setting of the pattern for the exercise feedback may include settingan output period of the tactile feedback. When the output pattern of thetactile pattern is set as the vibration pattern 1 210, the output speedof the tactile feedback may be relatively low, and the output period ofthe tactile feedback may be relatively long. When the output pattern ofthe tactile feedback is set as the vibration pattern 2 220, the outputspeed of the tactile feedback may be relatively high, and the outputperiod of the tactile feedback may be relatively short.

When the exercise intensity information of the user is greater than thetarget range, the exercise feedback provision apparatus may prolong theoutput period of the tactile feedback. When the exercise intensityinformation of the user is less than the target range, the exercisefeedback provision apparatus may shorten the output period of thetactile feedback. When the exercise intensity information of the user iswithin the target range, the exercise feedback provision apparatus maydisallow the tactile feedback to be output.

In an example, the mobile terminal 200 may output a message indicatingthe user may apply an input during a predetermined period of time, forexample, for ten seconds. The user may apply a touch input on thedisplay during the predetermined period of time. In response to theapplying, the mobile terminal 200 may sense an electrical signal, andset a vibration pattern such that the electrical signal corresponds tothe vibration pattern or the output pattern of the tactile feedback. Forexample, the user may arbitrarily apply the touch input to the mobileterminal 200 to set the output pattern. The mobile terminal 200 maysense an electrical signal corresponding to the touch input appliedarbitrarily, and set a vibration pattern based on the electrical signal.The exercise feedback provision apparatus may provide a tactile feedbackbased on the vibration pattern or an output pattern corresponding to thetouch input arbitrarily applied by the user.

Referring to FIG. 3 , a user wears an exercise feedback provisionapparatus 300 provided in a form of a wearable device. The user sets anoutput pattern of a tactile feedback in the exercise feedback provisionapparatus 300.

In the exercise feedback provision apparatus 300, a display displays aplurality of output patterns. The user may scroll up and down to selectan output pattern from the plurality of output patterns. Based on aselection input of the user, the exercise feedback provision apparatus300 sets the output pattern.

The exercise feedback provision apparatus 300 displays a user interfaceon the display, and sets the output pattern based on an input for theuser interface. As described with reference to FIG. 3 , the exercisefeedback provision apparatus 300 provides a list of preset vibrationpatterns. Also, the exercise feedback provision apparatus 300 displaysthe user interface on the display such that the user sets the outputpattern.

As an example, the exercise feedback provision apparatus 300sequentially displays a plurality of blocks on the display. The user mayselect a block from the blocks, and the exercise feedback provisionapparatus 300 may change a graphics property of the selected block. Forexample, the exercise feedback provision apparatus 300 may change acolor of the selected block. The block of which the graphics property ischanged may correspond to an output of the tactile feedback. Also, theuser may set an output intensity of the tactile feedback by selectingthe block. The exercise feedback provision apparatus may sense a periodof time of the user touching the block, and match the period and theoutput intensity of the tactile feedback. The exercise feedbackprovision apparatus 300 may match a case in which the period of time ofthe user touching the block is relatively long and a case in which theoutput intensity is relatively high.

In an example, the exercise feedback provision apparatus 300 may outputa message indicating the user is to touch the display to set the outputpattern. The user may apply a touch input to the display during apredetermined period of time, for example, ten seconds. The exercisefeedback provision apparatus 300 may sense an electrical signalgenerated in response to the touch input, and set the output patternsuch that the tactile feedback is output based on the electrical signal.For example, when an electrical signal “110011001100” is generated inresponse to the touch input of the user, the exercise feedback provisionapparatus may set the output pattern such that the tactile feedback isprovided based on the electrical signal “110011001100”. An input patternof the user may correspond to the output pattern of the tactilefeedback.

In an example, the exercise feedback provision apparatus 300 mayrecognize a step of the user using an acceleration sensor, and coach theuser for an exercise speed, using a vibration feedback. Also, theexercise feedback provision apparatus 300 may output a messageindicating the user is to take a step for each vibration time. Forexample, when a speed of taking a step is two beats per minute (bpm),and when a running speed is to be reduced due to a heart rate higherthan a target heart rate, the exercise feedback provision apparatus 300may output a vibration at an interval of 1.5 bpm, and send a feedbackindicating the user is to keep pace with the output vibration such thatthe user reduces the running speed.

FIG. 4 is a block diagram illustrating another example of an exercisefeedback provision apparatus 400. Referring to FIG. 4 , the exercisefeedback provision apparatus 400 includes an acquirer 410, a feedbackprovider 420, and a controller 430.

The acquirer 410 acquires exercise intensity information including atleast one of user biometric information and user movement information.From a user, the acquirer 410 may acquire at least one of heart rateinformation, maximum heart rate information, and information of a heartrate of an anaerobic oxygen threshold. Also, the acquirer 410 mayacquire, from the user, at least one of moving distance information,moving speed information, and step count information.

The feedback provider 420 outputs a tactile feedback at a referencespeed in response to the acquiring of the exercise intensityinformation. When an exercise application stored in the exercisefeedback provision apparatus 400 is executed, the feedback provider 420may output the tactile feedback at the reference speed. For example, thefeedback provider 420 may drive a vibration motor such that a vibrationis output at a speed of 60 bpm.

The controller 430 verifies whether the exercise intensity informationis in one of the target range, a range greater than the target range,and a range less than the target range. The target range corresponds toan optimal exercise intensity of the user. The target range may be arange of a target heart rate that is set based on a heart rate of theuser. Alternatively, the target range may be a range of a moving speedcorresponding to the range of the target heart rate of the user.

As an example, the controller 430 may verify whether a heartbeat of theuser is in a range greater than the target heart rate, the range of thetarget heart rate, or a range less than the target heart range. Asanother example, the controller 430 may verify whether the heartbeat ofthe user is in the range of the target heart rate or in a range otherthan the range of the target heart rate.

The controller 430 controls an output speed of the tactile feedbackbased on a result of the verifying. In a state in which the tactilefeedback is being output at the reference speed, the controller 430controls the output speed of the tactile feedback.

As an example, when the exercise intensity information of the user is inthe range greater than the target range, the controller 430 may generatea control signal to reduce the output speed of the tactile feedback.That is, when the exercise intensity information on the user is in therange greater than the target range, the controller 430 may control theoutput speed such that the tactile feedback is output at a speed lowerthan the reference speed. The feedback provider 420 may output thetactile feedback at a speed of 59 bpm, which is lower than the speed of60 bpm. When the exercise intensity information on the user is in therange less than the target range, the controller 430 may generate acontrol signal to increase the output speed of the tactile feedback.That is, when the exercise intensity information on the user is in therange less than the target range, the controller 430 may control theoutput speed such that the tactile feedback is output at a speed higherthan the reference speed. The feedback provider 420 may output thetactile feedback at a speed of 61 bpm, which is higher than the speed of60 bpm. When the exercise intensity information on the user is in thetarget range, the controller 430 may control the output speed such thatthe tactile feedback is output at the reference speed.

As another example, when the exercise intensity information is in therange other than the target range, the controller 430 may adaptivelychange the output speed such that the tactile feedback is output at aspeed different from the reference speed. Also, the controller 430 maypredict the moving speed of the user, and control the output speed ofthe tactile feedback based on the predicted moving speed.

The controller 430 may adaptively change the output speed of the tactilefeedback based on a change in the exercise intensity information. Forexample, when the exercise intensity information is in the range lessthan the target range, the output speed of the tactile feedback may beincreased when compared to the reference speed. When the exerciseintensity information is in the range less than the target range despitethe outputting of the tactile feedback, the controller 430 may sensethat the exercise intensity information is not changing in a desiringdirection. The controller 430 may increase the output speed of thetactile feedback based on a result of the sensing.

The exercise feedback provision apparatus 400 may further include a userinterface configured to receive, from the user, an input for setting theoutput speed. For example, the exercise feedback provision apparatus 400may further include a touch display. In response to a touch input of theuser on the touch display, the exercise feedback provision apparatus 400may set the output speed of the tactile feedback.

The exercise feedback provision apparatus 400 may further include acommunication interface configured to receive the output speed from anexternal device. The external device may be a wearable device and/or amobile terminal paired with the exercise feedback provision apparatus400. The external device may be a device included in an identicalnetwork, for example, a wireless body area network (WBAN), to theexercise feedback provision apparatus 400. The user may set the outputspeed of the tactile feedback, using the external device. The externaldevice may transmit the set output speed to the exercise feedbackprovision apparatus 400.

Since the descriptions provided with reference to FIGS. 1 through 3 arealso applicable to FIG. 4 , repeated descriptions will be omitted forincreased clarity and conciseness.

FIGS. 5 and 6 are diagrams illustrating examples of operating anexercise feedback provision apparatus. Referring to FIG. 5 , a userwears wearable devices 510 and 520 while exercising. The wearabledevices 510 and 520 provide an exercise feedback to the user.

The wearable device 510 includes a sensor 511 that measures a heart rateof the user, and a display 512 that displays the heart rate of the user.Also, the wearable device 510 may include a vibration motor to provide atactile feedback to the user.

The wearable device 510 measures the heart rate of the user as “110”. Arange of a target heart rate that corresponds to an optimal exerciseintensity of the user may be between “120” and “140”. Since the heartrate of the user is less than the range of the target heart rate, thewearable device 510 may provide the tactile feedback based on an outputpattern corresponding to the heart rate. The user may recognize theoutput pattern of the tactile feedback, and increase a running speed.The wearable device 510 may sense whether the heart rate of the userreaches the range of the target heart rate. Based on a result of thesensing, the wearable device 510 may suspend the tactile feedback. Theuser may increase the running speed until the tactile feedback issuspended.

The wearable device 520 outputs a message 521 indicating the user is toincrease the running speed. The wearable device 520 displays a currentrunning speed, and a target running speed corresponding to the optimalexercise intensity of the user.

Referring to FIG. 6 , a user wears a wearable device 610 whileexercising and using a health device 620. The wearable device 610 may beconnected with the health device 620 through a wired network and/or awireless network.

The wearable device 610 may verify whether a running speed of the useris in a target speed range. When the running speed of the user is in arange less than the target speed range, the wearable device 610 mayprovide a first tactile feedback to the user. The wearable device 610may transmit a message to the health device 620 to increase the runningspeed. When the running speed of the user is in a range greater than thetarget speed range, the wearable device 610 may provide a second tactilefeedback to the user. The wearable device 620 may transmit a message tothe health device 620 to reduce the running speed.
